HTML Formatter
Use HTML Formatter when you need to make messy code or data easier to read. Add the code or data, choose the option that matters, and review the formatted output.
Format HTML Code
Turn minified or chaotically-indented HTML into cleanly nested, readable markup - or minify it back for production. Indentation that finally matches the actual element structure.

What HTML Formatter checks
The formatter parses your HTML's element structure and re-indents it so nesting depth is visible at a glance - children indented under parents, siblings aligned, closing tags where you expect them. Minify mode does the reverse for shipping.
Why developers use it
Unreadable HTML hides structural bugs: an unclosed div that shoves the rest of the page into the wrong container is invisible in minified soup but obvious once indentation reveals the hierarchy - the misaligned closing tag just sits there looking wrong. Reading CMS output, emailed templates, or scraped markup without formatting first is voluntary suffering.
How the code or data is handled
Paste HTML, get formatted output. Processing runs in your browser, which matters when the markup contains real page content you'd rather not send to a random website. Format before debugging; minify before shipping.

"Format before you debug - most 'mystery' layout bugs are just structure you couldn't see yet."
